Hi I have 6 hickens living in a 4x8 coop- but no run yet. I just watch over them as I let them out during the day. I will get a run though- a fairly big one to. 12x20. I was wondering if I could house a goat or too ( mabey some sheep as well) in a 3 wall shelter in the run? (they wounldn't have acess to the chicken feed.
